Abstract: CONSTANT BEAMWIDTH ANTENNA                      Abstract of the Disclosure An antenna assembly for radio frequency energy is disclosed wherein individual antenna elements making up an array are fed in an improved manner so that the width of a directive beam, or beams, formed by such elements is, or are, maintained substantially constant over a wide band of operating frequencies.  The antenna assembly includes a printed circuit lens having a plurality of feedports coupled to a like plurality of the antenna elements through different constrained electrical paths.  The desired operating characteristic is attained by disposing radio frequency energy absorbing material of varying length in the constrained electrical paths, to selectively attenuate radio frequency energy to the antenna elements as operating frequency is changed, with the result that the width of the beam, or beams, radiated from the array of antenna elements remains substantially constant over a wide band of operating frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE        A boost pump incorporates a low-flow impeller pump for charging the inlet of a gas producer fuel pump and a high-flow impeller pump for charging the inlet of an augmentor fuel pump.

The drive shaft may be placed in driving connection with the high-flow pump through the medium of a friction clutch which is engageable by the application of a fluid pressure. Disengagement of the high-flow impeller, when augmentation is not required, significantly contributes to an increase in pump efficiency and a reduction in heating of the fluid being pumped.
